Chuckled at "requires refreshing for every comment to appear", lol what exactly are these guys spending their R&D dollars on??
I know massively scalable chat is hard to do but if http://www.livefanchat.com/ can do it it properly you'd think that Facebook would have no issues scaling and not need to kill this product (heck they paid $20m for the Hot Potato developers to buy the experience/technology).
September 2012 Breaking Changes (90-day notice) - Removing Live Stream plugin
The Live Stream plugin will be removed on September 5, 2012. We recommend using the Comments Box plugin instead. Please migrate your app as soon as possible. On September 5th, if your app is still using the Live Stream plugin, we will render the Comments Box plugin in its place. While it offers similar functionality, there are a few functional differences. Please see the Live Stream plugin documentation for more info.
Migration to Comments Box Plugin - https://developers.facebook.com/docs/reference/plugins/live-stream
On September 5, 2012, if you are still utilizing the Live Stream plugin, we will render the Comments Box Plugin instead. While the Comments Box plugin offers similar functionality, there are a few differences:
· Live Stream allowed you to specify an xid so that you may have multiple plugins on the same page. Comments box does not allow this.
· Comments Box does that have 'via attribution url' for specifying where outbound clicks should go
· Comments Box requires a refresh for updates
